Like Tristar said, everyone's different and I, for example, am not weighing myself for the first two weeks. My weigh-in will be my 'reward' at the end of the fortnight. I know I'm in ketosis and I already feel like I've lost weight just by touching my body (weird though that may sound, lol!) i.e. where was once completely squishy feels a little less soft and firmer.
I for one am someone who would get really hung up and competetive (with myself) about how much I was weighing and I don't want it to be like that. I'm not in a desperate hurry to lose loads of weight and intend to turn this into a way of eating for life, so I don't feel the need to monitor my weight every day or even every week. It's how I feel, look and what size I can get wear that count. Don't forget: muscle weighs more than fat
Good luck honey- you can do it....try to relax
